摘要: 以葡萄糖与疏水性辛烯基琥珀酸酐(OSA)为原料进行酯化改性,并将合成的辛烯基琥珀酸葡萄糖酯(OSGE)进行分离纯化,制备了糖酯含量约50%的OSGE;以十二烷基直链苯磺酸钠(LAS)、烷基糖苷(APG)和椰油酰胺丙基甜菜碱(CAB)为对照,研究其温和性与界面性质。结果表明,OSGE和LAS的表面张力均为28mN/m;临界胶束浓度(CMC值)的排序为OSGE<LAS<APG<CAB;OSGE的亲水亲油平衡值(HLB)为16.90,表明其亲水性最强;OSGE的乳化能力与LAS和APG无显著差异,但其刺激性远低于其他3种表面活性剂。

Abstract: Glucose and octenylsuccinate anhydride (OSA) were modified by esterification. The synthetic octenylsuccinate glucose ester (OSGE) was separated and purified to prepare OSGE with a sugar ester content of about 50%. Its irritation or interfacial properties were studied by taking linear sodium dodecylbenzene sulfonate (LAS), alkyl polyglucoside (APG) and cocamidopropyl betaine (CAB) as control group. Results show that the surface tension of OSGE and LAS is about 28mN/m; the critical micelle concentration (CMC) of surfactant follows the order: OSGE < LAS < APG < CAB; the hydrophile-lipophile balance (HLB) of OSGE is 16.90, indicating its highest hydrophilic property. No significant difference was found among OSGE, LAS and APG in emulsification ability, while irritation of OSGE is much lower than that of other three surfactants. 


Key words: surfactant, octenylsuccinate glucose ester, interfacial properties, hydrophilic property, emulsification ability, irritation
